Jerry - no problemo
Kreighoffs do seem to have occasional problems. I can believe a frame cracked. Maybe once every couple years there is news of one blowing up. Whether that indicates some inherent design flaw I can't say and really don't care since a KG is simply too ugly to own.
There have been instances as well I've heard of aftermarket sideplated Perazzi MX8s cracking frames. Critical metal is removed when the recesses for the plates are machined. Factory sideplated guns do not share that proclivity as the actions are not identical to the non-plated actions. Fortunately the difference is obvious.
Personally I find it surprising that any gunmaker survives in today's market.
